very fast C++ library for parsing the output of NCBI BLAST programs

This package provides a very fast library for parsing the default output of
NCBI BLAST programs into a C++ structure.

libzerg is faster, but it provides only lexing (i.e. it only returns pairs
of token identifiers and token string values). librostlab-blast uses a
parser generated with bison on top of a flex-generated lexer very similar to
that of libzerg.
